SPECIFICATION forming part ofLetters meant No. 284,368, dated September 4, 1883.

V I Application filed January 4, 1883. (No IDOGGL) 'To alZ. whomit may concern.-

Be. it known that we, HENRY S. BERNH RT and IsAAc R. BITTER, both of Reading, in the county of Berks and State of Pennsylvania, have invented a newand Improved Dumping Wagon, of which the following is a full,clear, and exact, description.

The object of our invention is tofacilitate the dumpingof the contents of a wagon or a cart. p

The invention consists in adumping-wagon which can be raised at the rear end by quad-j rant-racks mounted on the frame of the wagon and connectedwith the box, and at the front end by arms pivoted to the frame and to the box, which arms rest against rollers onatransverse shaft provided with rollers resting on tracks on the frame, which shaft is connected by chains with a transverse shaft on which are mounted the pinions for operating the quad rant-racks when thesaid shaft is turned. Both the front and rear ends of the wagon can be raised, or the front end only can be raised,by

responding parts in all thefigures.

the box.

disengaging the quadrant-racks from the pinions, for by turning the said. shaft the chains will be wound on the same, and will draw the shaft provided with the rollers, and which forms a truck with the said rollers, toward the rear end of the wagon-frame, and will thus sw ing the arms connected with the box up ward.

The invention also consists in combinations of various parts and details, as will be fully de-- scribed and set forth hereinafter.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate cor- Figure 1 is a longitudinal elevation of our improved dumping-wagon, showing'the front end of the box raised. Fig. 2 is a plan view of the wagon-frame, showing the box removed.

Fig. 3 is a detailcrosssectional elevation of the front end of thebox.

The wagon-box Ais constructed with a flat bottom, which is slightly inclined upwardat ,the longitudinal sides, whereby recesses d will be formed in the bottoin of the box alongthe sides, as shown inFig. The "boxA rests Fig. 4 l is a detail elevation of the i roller for operating the pivoted arms that raise upon a wagon frame, B, supported by wheels in the usual manner. At the rear end of the frame B a transverse shaft, 0, is journaled, the ends of the said shaft projecting from the sides of the frame B, and the said shaft isprovided at each end with an eccentric bushing, D, on

each of which a quadrantrack, E, is loosely mounted in such a manner that the racks extend toward the front end of the box. The upper arm of each rack E is provided at the free end with a slot, (1, through which apintle or stud, b, passes into theside of the box A,

as shown inFig. 1. The quadrant-racks E are adapted to engage with pinions F, mounted rigidly on the ends of a transverse shaft, G, journaled in the frame B, on which shaft G is also mounted a worm-wheel, H, engaging with a worm, J mounted on a shaft, K, journaled in hangers on the bottom of the frame B in such a manner that thesaid shaft K will be paralleli with the longitudinal axis of the frame. A squared end of the said shaft projects from the rear end of the frame, so that a key canb'e applied on this squared end of the a said shaft for the purpose of turning the shaft.

Two arms, L, are pivoted, attheir upper ends to the inner surfaces of the sides of the box, at

the front end of the same, the upper ends of i the said arms passing into the longitudinal recesses d, formed in the bottom of the box at the side edges. The lower ends of the arms are loosely mounted on a transverse shaft, M, held in hang= .ers N, below the side pieces of the frame B, so

that the said arms L can swing in the vertical plane. A track, 0, is secured to the inner surface of each side piece of the frame'B, which track is partly above and partly below the crosspiecc. Beginning at the rear end of the track, which is above the shaft M, the track extends slightly above the side piecesof the frame B, andthen tow ard the front end of the frame, then downbelow the frame and on about ahorizontal line toward the front end of the frame, and is then secured to the bottom of the same, as is shown in Fig. 3. On a transverse shaft, 1?, are loosely mounted two flanged rollers, which run on the tracks .0, and adjoining the inner side of each roller Qaflanged roller, B, isloosely mounted on the shaft 1?, against which flanged rollers B the arms'L rest, so that the rollers R will always be in front of the arms L, as shownin Figs. 1 and 2. Chains S are secured to the shaft P and to the shaft F. The shaft is pro- 1 rear end, through which spout the coal passes I vided with a handle, 0, for turning the same. The box A is provided with a spout, A, at the is turned, by means of the handle 0, to draw the of the box.

quadrant-racks E from the cog-wheels G and disengage them from the same, so that if the shaft F is turned by means of the worm and worm-wheel the cog-wheelcannot act on the quadrant-rack. If the shaft F is turned, the chains S will be wound on the same and will draw the shaft P from the front toward the rear end of the wagon-frame, and the rollers R, pressing against the arms L, swing the said arms upward and thereby raise the front end The shaft P and the rollers R Q forin a truck running on the tracks 0, and serving to swing the arms L upward. If the box is to be lowered, the shaft E is turned in the inverse direction, whereby the chains S will be unwound, and the weight of the wagon-box will swing, the arms L downward and push the trucks P Q R in the direction from the rear toward the front end of the wagon-frame. If both the front and rear ends of the box are to be raised, which is necessary in case the coal is to slide a long distance, the

racks E are engaged with the eog-wheelsG,-so

that when the shaft E is turned the racks E will be swung upward at the same time that the arms L areswung upward. When the box bottom of theframe B to interfere with turning the front wheels.

Having thus fully described our invention, we claim as new, and desire to secure by Letters Patent 1. I11 a dumpingwagon, the combination, with the box A, frame B, and arms L, pivoted to the said box and frame, of the transverse shaft P, arranged to move independently of the frames L and to bear against the sides of said arms after ascending the incline of the track,

said shaft being connected to operating mech anism, substantially as and for the purpose set forth. 7

2. In a dumping-wagon, the combination, with the body or box A, the frame B, and arms L, pivoted to said box and, to a depending bracket-or hanger, N, of the said frame, of the track 0, of an approximate S shape, with one arm of the S arranged below the frame and the other arm above the latter, and the transverse shaft P, having rolls Q B, one set bearing against the sides of the armsand theother set traveling upon the track, saidshaft being connected to operating mechanism, substantially asand for the purpose set forth.

In a dumping-wagon, the combination, with the bodyor box A, frame B, arms L, pivoted to said frame-and to a shaft, M, supported in bracketsN of the box or body, trackO,:and

transverse shaft P, having the rolls-Q B, and

adapted to move indep en dently-of the said arms and to bearagainst the sides of thexarmsafter ascending the incline of the track, ofthe toothed quadrants E, shaft G, having the pinions E and H, shaft K, having the worm J, and the chains S, substantially as and for ,the purpose -set forth.
